    Removes unicode 'u' response for "cinder get-capabilities"

    The output of "cinder get-capabilities" command returns
    unicoded response. But it would appear from the utils
    class that setting formatters will go through the
    capabilities dict and make sure all values are properly
    string formatted. Therefore added formatters to return
    string formatted response.

    Added formatters=sorted(prop.keys()) line instead of
    static values as suggested by the reviewer, to avoid
    tying server knowledge to the client and also any
    update on the server side would easily reflect here.
